A new type of abnormal drain current (ADC) effect in fully depleted (FD) silicon-on-insulator (SOI) MOSFETs is reported. It is found that the drain current becomes abnormally large for specific front- and back-gate voltages. The drain current exhibits a transient effect due to the floating body behavior and no longer follows the conventional interface coupling theory for these specific front- and back-gate bias conditions. It is shown that the ADC can be generated by the combination of gate-induced drain leakage, transient effects, and parasitic bipolar transistor action in FD SOI MOSFETs.
